Arabul, who was lodged in Alipore Central Jail, was granted conditional bail by the chief judicial magistrate, Alipore court, yesterday.
This was Arabul's fifth attempt in getting bail in the case, having been refused four times earlier.
He was, however, directed not to enter the Leather Complex police station area, under the jurisdiction of which the place of arson falls.
The former Bhangar MLA was accused of involvement in the burning of vehicles of CPI(M) supporters and assault.
He was earlier granted bail in the case.
